1/10 sounds much higher than I would expect in Chevron gas. Where did this number come from? Ed

I think the reference is to 1/10th the concentration recommended on the bottle. There are different versions out there, but the latest I remember is a 12 oz bottle with a recommendation to use it for up to 15 gallons of fuel. I also remember when the 12/20 oz bottles were recommended for 12/20 gallons. So for that one it would be 1 oz for ever 10 gallons.

Clean and lube. I prefer to run a few tanks on, then a few tanks off and play "can I detect a MPG gain" with my data. I did see some improvement with the above mix. ~ 3:1 ratio or so and ~ 1oz/3gal dose.

The bottles of Techron I have are the 20 oz. bottles which indicate they will treat 20 gallons. This equals 1 oz. / gallon.

My recommendation, based on information gleaned over the years from various sources (trust it or not, it's free advice and definitely worth at least what you're paying for it) is to use 1 oz. / 10 gallons as a continuous treatment dose. This is 1/10th the dose recommended on the bottle.

What makes you think 1 oz. / 10 gallons is higher than the amount in pump gas?

Edit to add:

If you are too lazy to Google it, here's what Chevron has to say on their Techron web site:

What is the difference between TechronŽ at the pump and Techron Concentrate Plus in the bottle?

The principal difference is additive concentration and rate of deposit clean-up. Gasolines with Techron over multiple fill-ups will help clean deposits on intake valves and minimize harmful combustion chambers deposits. When added to a full tank of gasoline, a bottle of TechronŽ Concentrate Plus results in an additive concentration roughly 10 times stronger. This mega-dose of Techron provides a much quicker clean up of intake valve deposits left by lower quality gasolines. In addition, the high concentration of Techron reduces combustion chamber deposits, which can help eliminate deposit-related engine knock.

I pour in an oz of Redline's Fuel System Cleaner into my 13.2 gallon tank at every fill up. Even though I use Shell or BP 95% of the time, I still add the cleaner at small doses simply to add a bit more cleaning additives into the mix.

I haven't done any testing to see if it adds gas mileage due to upper cylinder lubrication because my driving style is all over the place and my average MPGs jump around -7-8 points at practically every fill up... Hahaha.
